'fering knife and one crozing knife.

The invention also relates to certain details of construction, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the improved cutter head looking in the direction of the arrow V, Fig. 3, a section being taken through its supporting shaft. Fig. 2 is a side elevation of the improved cutter' head looking in the direction opposite to the arrow V, Fig. 3. Fig. 3 is an edge view of the improved cutter head looking in the direction of the arrow W, Fig. 2. Fig. 4 is a section on or about line a a, Fig. 2, the shaft being shown in full. Fig. 5 is an enlarged section on line b b, Fig. 2. Fig. 6 is an enlar ed transverse section on line 0 c, Fig. 1, showing the method'of securing the chamfering knife in place. Fig. 7 is an enlarged transverse section on line at d, Fig. 1. Fig. 8 is an enlarged transverse section on line e 2, Fig. 1, showing the method of securing the crozing knife in place. Fig. 9 is an enlarged detached edge view of the washer used in securing the chamferin knife in place. Fi 10 is a bottom view 0 the same. Fig. 1 is a fragmentary edge view of a barrel stave. after it has been operated upon by the, improwedgcutter head, showin the croze cut thereinfandthe inner ed 9 o the stave chamfered, i

n referring tp the drawings for the details of construction, like numerals designate like parts. i

The invention comprehends a split collar having enlargements to which a chamfering knife and a crozing knife are ad'ustably attached, and a stop for limiting t e depth of the cut. i

The split collar 1, is split at one side as shown at '2,in Figs. 1 and 2, and is con- Specification of Letters Patent.

Application filed May 16, 1907.

Patented Jan. 12, 1909.

Serial No. 374,027.

The collar is provided on the side about opposite the split with an enlargement 9, which is channeled or cut out on one face to form an inclined seat 10, against which a chainfering knife 11, is supported. The ehamfering knife 11, is held in lace by a. locking bolt 12, which passes tirough an opening in the enlargement and forces the beveled side 13, of a washer 14, fitted on the bolt 12, against the side of the charnfering knife. The opening through which the bolt 12, passes is countersunk sufliciently to receive the washer 14, as shown in F i 6.

The crozing knife 15, is supporte in a slot 16, formed in the opposite face of the enlargeintnt and is fastened in place by a locking bolt 17.

By referrin to F i 3, it will be seen that the cutting ed ge of tie crozin knife 15, is V-shaped so as to produce the V-shaped croze shown in Fi 11.

i It will be note by referring toFi 1' and 2, that the chamfering knife anf the crozing knife extend at a slight angle to each other and that the chamferi'ng knife is additionally tilted obliquely as shown in Fig. 3, so that it will chamfer or bevel the end of the stave pro erly.

A portion of the ace of the enlargement in proximity to the cuttin end of the crozlng knife is cut away ass own at 18, in Figs. 2, 3 and 6, to allow the chips to fly to one side. This prevents the clogging of the crozing knife.

-An enlargement 19, is formed on one side of the collar between the split enlargement 9 which is provided with an opening extendin therethrough in which a stop rod 20, is ailjustably fitted. The rod 20, is locked in place by a set screw 21, and adjusted by an adjusting screw 22 which bears against its inner end. The a justin screw 22, is fastened in place by a nut 23. r The outer projecting beveled to lit the inner surface of the bar- .rel, and by hearing against said inner sur- 2 and the i end of the rod 20,1;

face limits the depth of the croze out, see 1 This Fig. 1, where this action is shown.

stop rod acts only during the first revolution of the barrel, that is, while the rough cut is being made. During the second revolution of the barrel, or while the finishing cut is beingmade, this stop rod does not contact with the barrel, the cutter head being limited by a stop on the machine 1 to which it is attached.

The split collar 1, carries a stop screw 24, i see Figs, 1, 2, 3 and 7, the head of which bears against a part of the hearing in which the shaft 5, is supported. This stop screw 24, affords a fine l ngitudinal adjustment of the split collar upon the hub 3. it is locked against involuntary movement by a lock nut 25.

I claim as my invention.

1. A stationary cutter head for chamfering and crozing the ends of barrel staves comprising a collar having an enlargement,

a ehamfering knife supported on one side of i said enlargement, a oroaing, knife supported m the opposite side of said enlargement; 3; Suit: knives extendingat an angle to each other and the ehaz'nfering knife being additionally tilted to give a bevel cut to the barrel lat-ave and a stop rod supported from the collar at one side of said enlargement and :50 adapted. to bear against the barrel stave to limit the extent of cut.

2. A stationary cutter head comprising a split collar having an enlargement about 0p- 5 posite the split, a chamfering knife support- :45

ed on one face of said enlargement, a cr0zing knife supported on the other side of said i enlargement, and a stop rod adjustably sup 3 ported from the collar on one side of said enlargement.
